摘要： A lens driving device, a camera device, and an electronic apparatus, which are capable of ensuring smooth movement of a lens support wherein the lens driving device includes: a lens support; a frame member; and a guide mechanism configured to guide the lens support in such a manner that the lens support is freely movable in a direction orthogonal to an optical axis direction of the lens relative to a predetermined member forming the frame member. The guide mechanism includes, on each of one side and another side in a direction orthogonal to a moving direction of the lens support: a guide protrusion which extends along the moving direction of the lens support, and protrudes in the optical axis direction; and a guide groove formed in such a manner as to recess in the optical axis direction to allow the guide protrusion to be fitted to the guide groove. When viewed from the direction in which the guide protrusion and the guide groove extend, the guide protrusion and the guide groove are brought into line contact with each other at two positions on the one side in the direction orthogonal to the moving direction of the lens support, and are brought into surface contact with each other on the another side.

摘要： An aperture switching device is described that includes a base, a casing fitted to cover the base, and clamping parts fixed to the base. The clamping parts are driving power source input terminals and a shape memory alloy wire with two ends electrically connects the clamping parts. The base has a first light transmission hole, a rotary connecting part, a sliding groove, and a position regulating part. The casing has a second light transmission hole that corresponds to the first light transmission hole. A movable bump is connected to the shape memory alloy wire and slidably disposed within the sliding groove. An elastic member is disposed between the position regulating part and the movable bump. An optical aperture switching unit is positioned with one end portion mounted on the rotary connecting part and the end portion includes a switching slot mounted on the movable bump.

摘要： Disclosed are a lens driving device, a camera device and an electronic apparatus equipped with the lens driving device. When the lens driving device is mounted on the circuit board, the power supply terminal is less likely to fall off from the base. The lens driving device of the present disclosure includes a base, a lens support, and a driving mechanism that drives the lens support in the optical axial direction. The base is integrally provided with a power supply terminal mounted on an external circuit board and used for supplying power to the driving mechanism. A fall-off preventive portion is formed in at least a part of a contact portion that is in contact with the base on the power supply terminal.

摘要： A position detecting device includes a coil and a conductive member. The coil is formed within a surface being directed so that an M direction orthogonal to an L direction which is the moving direction thereof coincides with the normal direction thereof and has a meander wiring part. The meander wiring part has turning sections formed at ends thereof and turning width parts extending from the both ends of each turning section. Each turning width part has straight section extending in parallel to each other. The conductive member confronts against the coil with a space therebetween in the M direction, an edge of the conductive member is configured to be confronted against the straight section of the meander wiring part and extended along the non-parallel direction with respect to the extending direction of the straight section and the L direction to traverse a plurality of straight sections.
